8 ADJUSTING FOR STABILITY

GaIn - raTeD SPeeD & IDle SPeeD

Once the engine is running at operating speed and at no load, the following governor performance adjustments can be made to in-crease engine stability.

GaIn TYPe aDjUSTmenT ProceDUreRATED SPEED

1. Selected when IDLE input is disconnected.

IDLE SPEED

1.2.3.

Connect the idle input to ground.Change GAIN value.Disconnect Idle input from ground to switch back to Rated.Idle icon will blink.

The EEG6500 is equipped with two separate gains, one for rated speed, the other for idle speed. Both are set using the GAIN setting on the Quikset Menu.

QUIKSeT menUParameTer aDjUSTmenT ProceDUre

A. GAIN

1.2.3.4.

Increase this parameter until instability develops. Then, gradually decrease this parameter until stability returns.Finally, decrease this parameter one increment further to ensure stable performance. If instability persists, adjust the next parameter.

B. STABILITY 1.2.

Follow the same adjustment procedure as the GAIN parameter.If instability persists, adjust the next parameter.

C. DEADTImE 1. If fast instability occurs, switch DEADTImE to low and repeat steps A & B.

Normally, adjustments made at no load achieve satisfactory performance. For further performance see the System Troubleshooting section.noTe

9 ADJUSTING FOR DROOP

eXamPle

After the initial set up is completed and the # of Teeth, Crank Termination Speed and Rated Speed are set, position the external switch connecting Terminals H and K on to activate the DROOP mode following these sequence steps.

1. Go to the Advanced menu: Press and hold all three buttons simultaneously for two seconds to switch to Advanced menu.2. Confirm that the VSPD (Variable Speed / Fixed Speed Control) is OFF. Default position is off. 3. Confirm that the LEAD circuit is OFF. Default position is on.4. Set the NLCU (No Load Current) to the measured / displayed current value when operating at no load rated speed (default value

is 0.5 amps.)5. Set the FLCU (Full Load Current) to the measured / displayed current value when operating at full load rated speed (default

value is 4.0 amps.)6. Return to the main menu: Press and hold all three buttons simultaneously for two seconds to switch to the main menu.7. Select and set DROOP to the desired percentage.8. Change the Speed parameter, which turns into the DROOP OFFSET.9. This sets the RPm, above operating speed, to which the system will be commanded when DROOP is enabled. This is an offset

value.

1500 RPm operating speed x 0.05 (5.0% droop) = 75 RPm Input 75 RPm, this is the offset value.

The nlcU entered must be less than the flcU and the difference between the two must be at least 0.5 A. If an invalid combination is entered a warning will be flagged and the parameters will be default to 0.5 A and 4.0 A.

lIGHT force Governor

Turning the Light Force Governor (LFG) feature ON (default is OFF) scales the governor’s proportional response (GAIN) for the best resolution when controlling small actuators, like the T1 ATB, ALR/ALN, 100/103/104 series and normally closed Cummins EFC actuators. Turn the LFG feature ON for use with these low current actuators.

The letters LFG display in place of the Primary Parameter Units when adjusting GAIN and STABILITY to indicate the feature is ON. The LFG Feature can only be be turned ON or OFF when the engine is not running.

leaD cIrcUIT

Turning the Lead Circuit (LEAD) ON (default is ON) enables the governor to be more responsive and typically increases the range of GAIN adjustment. Turn Lead Circuit ON when there is slow or moderate hunting at higher GAIN settings.

1. Increasing the GAIN should reduce the instability but not totally correct it. If this is the case, there is most likely a problem with the engine itself. Check for: a. engine mis-firings b. an erratic fuel system c. load changes on the generator set voltage regulator.

If unsuccessful in solving instability, contact GAC for [email protected] or call: 1-413-233-1888

13 SYSTEm TROUBLESHOOTING

If the engine governing system does not function, the fault may be determined by performing the voltage tests described in Steps 1 through 3. Positive (+) and negative (-) refer to meter polarity. Should normal values be indicated during troubleshooting steps, then the fault may be with the actuator or the wiring to the actuator. Tests are performed with battery power on and the engine off, except where noted. See actuator publication for testing procedure on the actuator.
